The Broadway Tunnel is a roadway tunnel in San Francisco, California. The tunnel opened in 1952, and serves as a high-capacity conduit for traffic between Chinatown and North Beach to the east and Russian Hill and Van Ness to the west. In a proposal of the city's 1948 Transportation Plan, the tunnel was to serve as a link between the Embarcadero Freeway and the Central Freeway.The Broadway Tunnel was named in honor of Robert C. Levy in January 1986. Mr. Levy was the City Engineer and Superintendent of Building Inspection for the City and County of San Francisco. A plaque outside the tunnel reads, "He devoted his life to high standards of professionalism in engineering and to the City which he loved."The east portal is located at 37.797,-122.412, just east of the Mason Street overpass. The west portal is located at 37.796,-122.418, just east of the Hyde Street overpass. Combined with these two overpasses, the tunnel provides for uninterrupted traffic flow along Broadway for a stretch of six blocks, between Powell Street on the east and Larkin Street on the west.There is also a narrow sidewalk on both sides of the tunnel.
